If you don't clean your brass, every time you resize a case you're pressing carbon into the sizing ring. One day you'll stick a case on the sizing die.

I've noticed several pistols lately which have interesting configurations for their firing pins and firing pin holes. Some leave weird box imprints, some leave circles.

I don't think your loads have any problems.
